Dynamical mean-field theory for dense spin systems at finite temperature

In recent years, a method for computing spin dynamics at infinite temperature (spinDMFT) was developed. It utilizes the ideas of dynamical mean-field theory for fermions: single-site approximation and a self-consistency condition to approximate time-dependent spin correlations. I...

Experimental Signature of Transient Symmetry Breaking in a Cavity Dirty-Limit Superconductor

Abstract Transient states of matter far from equilibrium may exhibit physical properties beyond those allowed by the equilibrium-state crystalline symmetries. We explore ultrafast and direct electronic excitations of transient states in a dirty-limit superconductor with time-reso...

Control of the Néel Vector in the Quantum Antiferromagnetic Honeycomb Lattice

The switching of antiferromagnetic order and its efficient control promise to enable ultrafast manipulation of data and large storage capacity. Recently, the time-dependent Schwinger boson mean-field theory has been successfully developed to study the Néel vector switching in hyp...
